Re 4/4 diagram query

David Prior
 

The 420 diagrams contain an odd-looking pair of services that don’t appear in the online timetable. Anyone know if 220 / 221 actually run or not ?

612.1
220(DA) Domodossola – Vallorbe 01.17 – 04.10

612.3
221​Vallorbe – Domodossola 23.41 – 02.53

612.4
220​(EA) Domodossola – Vallorbe 01.17 – 04.10
